Cooler Master V8

The Cooler Master VS is a large CPU cooler. How large, you ask? Think the this is a knife" scene from "'Crocodile Dundee." Its 158mm height may make it
difficult to fit into your system, but we found that the V8 has plenty to offer those looking to overclock their processor with air cooling.

Under the VS's hood, which is des- igned to resemble an engine cover, are eight copper heatpipes and four sets of aluminum fins. A 120mm fan sandwiched in the middle of the V8 blowscool air through the fins. There's also a fan speed controller to let you adjust the fan from 80Orpm to 1,8OOrpm. When operating at 880Orpm, the V8 was nearly silent, and the 1,80Orpm setting wasn't too much louder.

The VS includes mounting brackets for Intel Socket 775 and AMD 940/AM2/AM2+ sockets. To install the V8, you'll need to remove the motherboard from your case,
place the appropriate plate on the back of your motherboard, and screw the CPU cooler to the plate. Although we would have appreciated an easier installation process, we were certain the V8 was securely held in place.

We tested the V8 with an Intel Core 2 Extreme QX9650 and a Gigabyte GA-EP45T Extreme motherboard. We also note the case featured a large wire mesh
vent on the side panel. At the processor's stock 3Gliz speed, the processor temperature was 35 degrees Celsius at idle and 42 C during Prime 95's stress test. When we ramped up the QX9650 to 3.9GHz, idle temps ran at a cool 37 C and an impressive 50 C average (55 (Thigh) during our overclocked Prime 95 stress test.

Considering the nearly 1GHz overciock. the V8's results are noteworthy. The only downside to the V8 is its large size, so make sure you have room in your case before purchase.

CoolIT Pure

CoolIT Pure
Quiet-running cooler good for midrange rigs



COOLIT'S $134.99 PURE CPU COOLER is a pre-assembled, all-in-one liquid cooling kit that bolts onto your case and CPU in a few steps, making it relatively easy way to upgrade your rig's cooling system. But while it's quiet and rather affordable, its performance isn't very different from a high-end heat-sink-and-fan combination.
The Pure works on all Intel LGA775 motherboards; AMD boards are also supported, but the instructions only mention Socket AM2 types. Motherboard removal is required for both platforms, which is unfortunate but rather common when installing a high-end cooler these days.
Once you've removed the motherboard, you'll have to install standoffs aroun the CPU socket with the included wrench and attach the Fluid Heat Exchanger (or waterblock) to the CPU. Then, remove your 120mm case fan and attach the cooler's apparatus to your case using the four included scres (if your case has either an 80mm or 92mm fan, it won't work with this cooler), attach a four-pin Molex power connector to the unit to power the fan and pump, and you're done.
Most of the hour-long installatio time was spent removing our motherboard; installing the cooler only took about 15 minutes, and the photo-filled manual was a great help. We were pleased with the Pure's low noise level and attractive appearance, but it didn't cool our Intel Core 2 Duo E6700 test processor much more than the stock Intel heat sink and fan could. (When idle, the CPU ran six degrees cooler; at full load, is was nine degrees.) The 120mm fan doesn't spin up at all as temperatures rise, which hurts cooling performance a bit, but keep the Pure running whisper-quiet.
